That game on Sept. 6, 1995, featured one of baseball's most iconic moments, as Ripken passed New York Yankees legend Lou Gehrig.

Ripken will throw out the ceremonial first pitch prior to the Orioles-Rays game on Sept. 1 as one of many celebrations.

Starting Thursday, the Orioles are holding a special 2131 sweepstakes, in which fans are encouraged to submit their photos from the historic record-breaking game, record-tying game, other Streak Week games or activities or any photos taken with Ripken on Twitter or Instagram by using #My2131. The Orioles will select one fan to receive four tickets to the Sept. 1 game, along with a pregame on-field experience and an autographed copy of the Cal Ripken Jr. authentic retirement commemorative program.

Additionally, the 2,131st person to check in using the MLB Ballpark app this weekend, when the Orioles host the Washington Nationals, will win four tickets to the game on Sept. 1 and a Cal Ripken Jr. autographed commemorative item.
